I have the Hobie electric motor mount, which is actually not made by Hobie but by a guy in Montana. I've had mine for a couple of years now and have never had a problem with nose diving due to this system. It has worked great for me! You can see it at http://www.sail-s.com/main/cart-s/h16TRAPSEAT/trapse.htm in the H16 section of the site. This is the only system I know of even though I know some have tried a rear mount system unsuccessfully.
